Amazon’s Sidewalk Will Soon Share Your Internet With Your NeighborsQuote:Amazon Sidewalk is still an experiment but that experiment is set to go live in the US on June 8. Not only are all Amazon Echo and Ring devices eligible, they are actually enrolled by default. Users will have to explicitly change their settings to opt-out and Amazon is probably hoping that they will also fall back on their default behavior of not changing default settings anyway.
If you have the newer devices that support this I'd turn it off or the FBI might smash your doors and arrest you because a neighboor is downloading kiddie porn.
